    Three high-dimensional glyphs for viewing software project management data assist in perhaps the most challenging engineering task in modern times managing large software projects. In data exploration, glyphs refer to graphical objects or symbols that represent data through visual parameters that are either spatial (positions x or y), retinal (color and size), or temporal. Common examples of graph... View full abstract»

    The value of information visualization depends on the success of its applications. One important application area is business visualization (bizviz). The author discusses the results of a survey that asked conference attendees to estimate the number of bizviz users and developers in their organization, their implementation stage, their application, and their most important issue View full abstract»

  • Interactive 3D visualization of optical phenomena

    Publication Year: 1998, Page(s):66 - 69
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (452 KB)

    Each year at colleges and universities nationwide, some 10,000 students take a course on optics, typically through a physics department. The method of instruction has changed very little in the past 40 years, and many of the textbook illustrations have remained essentially the same during this time. In particular, the illustrations rely heavily on line drawings and 2D graphs. Certain key concepts ... View full abstract»

    We discuss volume line integral convolution (LIC) techniques for effectively visualizing 3D flow, including using visibility-impeding halos and efficient asymmetric filter kernels. Specifically, we suggest techniques for selectively emphasizing critical regions of interest in a flow; facilitating the accurate perception of the 3D depth and orientation of overlapping streamlines; efficiently incorp...

    Software tightly integrated with simulation packages has dominated finite element postprocessing. Many of these packages have not kept up with the state-of-the-art developments in graphics technology and visualization techniques. Large and time-dependent data sets resulting from crash-worthiness simulations in the automotive development process demand new visualization tools that allow interactive... View full abstract»

  • Exploring large graphs in 3D hyperbolic space

    Drawing graphs as nodes connected by links is visually compelling but computationally difficult. Hyperbolic space and spanning trees can reduce visual clutter, speed up layout, and provide fluid interaction. This article briefly describes a software system that explicitly attempts to handle much larger graphs than previous systems and support dynamic exploration rather than final presentation. It ...

    The blast that destroyed Unit 4 of the Chernobyl Nuclear Power Plant (CNPP) 12 years ago prompted a firestorm of scientific, technological, political, and economic proposals for managing the worst nuclear accident to date. Following a meeting of the G-7 nations-the United States, Canada, Britain, France, Italy, Germany, and Japan-and Ukrainian representatives, the US Department of Energy (DOE) and...

    Very large hypermedia collections, say many thousands of documents and links, are often unmanageable. Users can have considerable difficulty finding particular information and comprehending its extent and scope. Support for explicit hierarchical structure of the collection, such as the Yahoo classification scheme, helps users by suggesting specific paths through the information space. Such hierarc...

    This case study presents applications of the eigenvector method to recent aeronautical studies at NASA Ames Research Center and Rensselaer Polytechnic Institute. We highlight its usefulness for detecting flow features such as vortex cores, vortex bursts, spiral vortex breakdowns, and vortex diffusion. The eigenvector method has also been used as a data analysis tool to guide an automatic mesh refi... View full abstract»

    Tele-immersion-the union of networked virtual reality (VR) and video to support collaboration among scientists, engineers, and educators-is an important element in the computing information infrastructure envisioned by the National Computational Science Alliance. Tele-immersion will let people from around the world casually enter a shared virtual environment (VE), manipulate that environment-wheth... View full abstract»

    In a previous paper I discussed the topic of aperiodic tiling for the plane (Glassner, 1998). This technique helps us create patterns with lots of theme and variation, like the leaves on a tree. I continue discussing the subject. The basic approach is to take a bunch of 2D shapes and impose rules on how they can connect, like the pieces of a jigsaw puzzle View full abstract»

    Visualized data and information can be inaccurate or even wrong. Moreover, in the synthetic digital world anybody can visualize anything in any shape or form, disregarding how users might perceive or get the information. Worse, as technology develops, it becomes easier to do so. Understanding the data and information and reaching sound decisions require knowing what pieces of information or data a...
